Introducing the Laburnum X watereri Goldenchain Tree, also known as Waterer Laburnum or Waterer Golden Chain Tree. This stunning deciduous tree boasts yellow pea-flowers in pendulous leafless racemes, which bloom in spring and make it a popular addition to gardens and parks. Most garden specimens are hybrids, combining the longer racemes of L. alpinum with the denser flowers of L. anagyroides. The Laburnum X watereri Goldenchain Tree is a low seed producer, making it a safer option. However, it's important to note that all parts of the plant are poisonous due to the presence of cytisine, a nicotinic receptor agonist. Symptoms of poisoning include intense sleepiness, vomiting, convulsive movements, coma, slight frothing at the mouth, and unequally dilated pupils, and diarrhea in severe cases. Despite this, it is still cultivated for its stunning appearance and attractive dark chocolate brown heartwood, which can be used for woodworking and musical instruments. Laburnum trees prefer moderate winter and summer temperatures with occasional deep watering in hot and dry summers. The Laburnum X watereri Goldenchain Tree has gained the Royal Horticultural Society's Award of Garden Merit and is ideal for aesthetic outdoor design projects.
